Essential Oil Composition of Vernonia Arabica from Dhofar, Oman

Vernonia arabica essential oil contains 39.48% oxygenated sesquiterpenes, with shyobunol (9.59%) and endo-1-bourbonanol isomers (9.13% and 4.64%) as main metabolites. This is the first report on the chemical composition of the aerial parts of this species, authored by Natale Badalamenti and shared under a CC-BY-4.0 license. The data was last updated on May 23, 2026.

Use Cases

• Compare chemical profiles of different Vernonia species based on the described metabolite concentrations.
• Identify unique chemical markers for plant taxonomy based on the detection of shyobunol and endo-1-bourbonanol.
• Study the geographic variation in essential oil composition based on the sample collected from the Dhofar region of Oman.

Strengths

• Quantitative composition data is provided, including specific percentages for shyobunol (9.59%) and endo-1-bourbonanol isomers (9.13% and 4.64%).
• The description indicates this is the first report for this species, providing novel data.
• The data is shared under a permissive CC-BY-4.0 license.

Limitations

• The dataset is small (1.4 MB) and consists of document files (PDF, DOCX), not structured data tables.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
